Theoretical Machine Learning Seminar

Rahul Kidambi
12:15pm|Princeton University, CS 302

The current era of large scale machine learning powered by Deep Learning methods has brought about tremendous advances, driven by the lightweight Stochastic Gradient Descent (SGD) method. Despite relying on a simple algorithmic primitive, this era...

Variational Methods in Geometry Seminar

Isoperimetry and boundaries with almost constant mean curvature
3:30pm|Simonyi Hall 101

We review various recent results aimed at understanding bubbling into spheres for boundaries with almost constant mean curvature. These are based on joint works with Giulio Ciraolo (U Palermo), Matias Delgadino (Imperial College London), Brian...

Variational Methods in Geometry Seminar

Min-max solutions of the Ginzburg-Landau equations on closed manifolds
Daniel Stern
1:00pm|Simonyi Hall 101

We will describe recent progress on the existence theory and asymptotic analysis for solutions of the complex Ginzburg-Landau equations on closed manifolds, emphasizing connections to the existence of weak minimal submanifolds of codimension two. On...

Computer Science/Discrete Mathematics Seminar II

Why can't we prove tensor rank and Waring rank lower bounds?
Visu Makam
10:30am|Simonyi Hall 101

One of the major goals of complexity theory is to prove lower bounds for various models of computation. The theory often proceeds in buckets of three steps. The first is to come up with a collection of techniques. The second is to be frustrated at...

Joint IAS/Princeton University Algebraic Geometry Seminar

On the algebraic Sato–Tate conjecture for abelian varieties
Victoria Cantoral-Farfán
5:00pm|Princeton University, Fine 314

The Sato–Tate conjecture, originally stated for elliptic curves on 1963, predicts the equidistribution of the normalized Frobenius traces with respect to the Sato–Tate measure, given by the pushforward of the Haar measure on SU(2). We would like to...

Symplectic Dynamics/Geometry Seminar

Getting a handle on contact manifolds
Kevin Sackel
3:30pm|Princeton University, Fine 224

Analogous to Weinstein structures in symplectic geometry, there is a notion of convex structures in contact geometry. We discuss an explicit surgery theory for contact manifolds with convex structures, showing that they naturally decompose into...

Quantum Jacobi forms and applications
Amanda Folsom
2:00pm|Simonyi Hall 101

Quantum modular forms were defined in 2010 by Zagier; they are somewhat analogous to ordinary modular forms, but they are defined on the rational numbers Q as opposed to the upper half complex plane H, and they transform in Q under the action of the...
